Overpaid Vendor by $0.50 - No Writeoff option in Payables

I overpaid a vendor by 50 cents and now have a debit balance in their account.  I just want to write off this amount but I don’t see a Writeoff option like in Sales.  What is the best way to write this off?  Debit Memo?  Credit their AP account and Debit an expense account? Thanks
